Multiservice access and aggregation node MA4000-RX is designed to build an access network via the GPON technology. The system allows building scalable, fault-tolerant “last mile” networks ensuring a high level of safety both in rural and urban areas. The access node provides management of subscriber devices, traffic switching and connection to the transport network.

The central element of MA4000-PX is a scalable Ethernet level L2 + (PP4X) switch, working in conjunction with the interface modules of optical access PLC8 for connecting subscriber devices via GPON technology.

The modules are installed in a standard 19″ VME-bus 9U case. The enclosure provides two slots for PP4X switch control modules and 16 slots for line modules PLC8 (GPON). The system may have one or two modules of the PP4X core switch. Installation of two modules allows building a highly reliable system through redundancy switches and to increase system capacity by distributing data flows between modules by stacking them.

Interaction between modules occurs through 10Gbit/s connection.

The central switching module is one of the platform's core elements. It carries out control and diagnostic tasks for the peripheral, switching and traffic aggregation modules. Installation of two modules improves fault-tolerance due to switch redundancy and the system's bandwidth capacity due to distribution of data streams between modules via stacking. Module interaction is realized via two 10 Gbit/s interfaces. Modules work in split and redundancy mode communicating via two internal 10 Gbit/s interfaces.
